The Caliber 3136: The Heart of the Modern Datejust
The Rolex caliber 3136 is a significant advancement in the brand's automatic movements. It represents a culmination of Rolex's decades of horological expertise, boasting improvements in precision, reliability, and power reserve compared to its predecessors. Key features include:
* Chronometer Certification: Like all Rolex movements, the 3136 is a Superlative Chronometer officially certified by COSC (Contrôle Officiel Suisse des Chronomètres), ensuring exceptional accuracy within stringent tolerances. This certification is a testament to Rolex's commitment to quality and precision.
* Paramagnetic Blue Parachrom Hairspring: This innovative hairspring, made from a paramagnetic alloy, is significantly more resistant to magnetic fields than traditional hairsprings. This enhanced resistance contributes to the watch's overall robustness and accuracy in a world increasingly saturated with electronic devices.
* Enhanced Power Reserve: The 3136 boasts an improved power reserve compared to previous generations, typically around 48 hours. This means the watch can continue to function accurately even if it's not worn for a couple of days.
* Improved Shock Resistance: Rolex has continually refined its shock absorption mechanisms, and the 3136 benefits from these advancements, making it more resilient to impacts and everyday wear and tear.
* Precise Date Change: The instantaneous date change mechanism is seamlessly integrated, ensuring a crisp and accurate date transition at midnight.
